High modulus ductile thermoplastic compositions having transparency to radio frequency signals

A thermoplastic composition comprising:

• a) from about 5 wt % to about 30 wt % of a thermoplastic polymer component comprising polycarbonate, polyethylene terephthalate or a combination thereof;
• b) from about 10 wt % to about 35 wt % of a polybutylene terephthalate component;
• c) from about 0.1 wt % to about 10 wt % of a polyester elastomer component;
• d) from 0 wt % to about 10 wt % of an acrylic impact modifier component;
• e) from 0 wt % to about 10 wt % of an ethylene/alkyl acrylate/glycidyl methacrylate terpolymer compatibilizer component;
• and
• f) from about 55 wt % to about 75 wt % of a ceramic fiber component,
• wherein,
• a molded sample of the thermoplastic composition has a tensile modulus of at least about 25 gigapascals (GPa) as determined in accordance with ASTM D638 and a tensile elongation at break of at least about 1.98% as determined in accordance with ASTM D638,
• the composition has a melt volume rate (MVR) of from about 12 cm3/10 min to about 25 cm3/10 min as evaluated at 275° C. under a 5 kilogram (kg) load, and
• the combined weight percent value of all components does not exceed 100 wt %, and all weight percent values are based on the total weight of the composition.
